Asymptomatic Hypocalcemia Persisting After Initial Oral Calcium Supplementation

This protocol addresses the patient with mild, asymptomatic acute hypocalcemia whose serum calcium has not reached the target level after an initial course of oral calcium supplementation — requiring escalation of the calcium replacement strategy.

Clinical Scenario

The patient is asymptomatic with serum calcium above 1.9 mmol/L — consistent with mild hypocalcemia. Despite initial oral calcium replacement, calcium has not improved to the target threshold.

Previous Treatment & Why It Was Insufficient

First-line management commenced oral calcium supplements — including Sandocal 1000 and equivalent preparations — with the goal of restoring adjusted serum calcium above 2.1 mmol/L on repeat measurement. That target was not achieved, triggering escalation to this next protocol step.

Next-Step Approach (Partial Summary)

The next step involves an upward adjustment to the existing oral calcium preparation — Sandocal 1000 — already in use. The full regimen, including the revised dosing schedule, is available in the complete protocol below.

'Mild' hypocalcaemia: asymptomatic; serum calcium >1.9 mmol/L.

If serum calcium remains between 1.9 and 2.1 mmol/L increase Sandocal 1000 to three BD.
